ELEVATING APPARATUS.

No. 303,384. Patented Aug. 12, 1884.

IRA BISHOP, OF SAN FRANCISCO, CALIFORNIA.

ELEVATlNG APPARATUS.

SPECIFICATION forming part of Letters Patent No. 303,384, dated August 12, 1884.

A Application filed June 20, 1884. No model.)

To all whom it may concern:

Be it known that I, IRA' BIsHoP, of the city and county of San Francisco, and State of California, have invented an Improvement in Ele vating Apparatus; and I hereby declare the following to be afull, clear, and exact descrip* tion thereof. K

My invention relates to a new and useful ele vating apparatus, the special object of which is to carry sacks or bags of material-such as grain from a lower plane and deposit them on a higher plane a result necessary to be accomplished in grain-warehouses, where the sacks have to be elevated to the floor above or to the top of a pile on the same floor.

The class of elevating apparatus to which my invention relates is exemplified by that apparatus for which Letters Patent of the United States No. 285,87 3 were issued to me October 2, 1883, and my present invention is an im-. provement in the line of said apparatus.

My invention consists in an endless chain belt or carrier having peculiar sack hooks or rests, and mounted by means of a suitable driving mechanism upon aportable frame, to which are attached top and bottom adjustable receiving and discharging aprons, as I shall hereinafter fully explain by reference to the accompanying drawings, in which Figure 1 is aperspective view of my elevating apparatus. Fig. 2 is a perspective view of a portion of the chain c and cross-bar F,

showing the manner of fastening. Fig. 3 is a horizontal section of same. Fig. 4 is a detail showing the connection of the hooks or rests G with bars F F.

A is an upright frame mounted on casters a, whereby it is readily portable. Through the base of the frame, near its corners, pass sharppointed spurs B, which are adapted to be screwed down to enter the floor or ground and raise the frame off its casters, and thus secure these bars are secured to the chains is shown in Figs. 2, 3. A cross-head or yoke, f,-is notched, and extends across the back of a link of the chain, and the bars are bound or clamped against the front of the link by a bolt, f, passing through them to the yoke, and tightened by a nut, f.

G. are the sack hooks or rests, consisting of bent or'curved bars, the tops of which are curved or looped loosely around the upper bar, F, and held by a bolt, g, Fig. 4, thus forming a pivot or hinge connection to allow for the necessary conformity as the chains pass around the pulleys. The hooks or rests are guided upon and past the lower bar, F, by means of staples g, loosely embracing them, and the said bar is slightly out out to receive the hooks. rests project outwardly from the bars, and have The lower ends of the hooks or a slight upward tendency. I have here shown but two sets of hooks or rests, arranged with relation to each other in such manner that as one receives a sack below the other discharges it above, though it is obvious I might provide a greater number of these sets. The staples g prevent the hooks or rests from falling away from their places, and yet allow them to move as they turn on their upper hinges, conform ing themselves to the course of travel of the chains around the pulleys.

H is the lower or receiving apron, hinged by arms h to the sides of frame A, and supported by legs or braces h bearingagainst said sides below. The apron is provided with an inwardly-projecting tongue portion, h, upon each side of which the books or rests Gpass, and which enables the sack to be supported in position to be taken .up by and upon the upwardly-moving rests. The object of hinging the apron is to permit it to be turnednp out of the way when not in use-a necessity which exists to allow free passage when the apparatus is standing in the narrow alleys between the piles of sacks.

K is the upper or discharging apron. This is hinged by arms k to the top of frame A, and its inclination may be varied by means of the supporting-braces k perforated as shown, 7

whereby they are adapted to be secured at various points in their lengths by the bolts If.

The apron is provided with a tongue portion,

20 they leave it.

k, upon which the sack is deposited and supportedwhile the hooks or rests leave it, passing down on each side of the tongue.

The object in providing for various inclina- 5 tions of the upper apron is to adjust the grade to the top of whatever pile of sacks the apparatus is supplying.

The driving mechanism is all below, and it consists of the shaft L, pinion M on said shaft,

IO and gear N on the pulleyshaft E. Anysuitable power may be applied to shaft L, and I have here shown crank l for this purpose, adapting the apparatus for hand-power.

The operation is as follows: The sack is fed, to apron H and pushed forward upon the These rods serve also to brace and stiffen the frame A.

The entire apparatus is made light 3 bination with the frame A and endless travelstrong, and it can readily be moved from place to place, and quickly fixed by its spurs.

Having thus described myinvention,what I claim as new, and desire to secure by Letters Patent, is

1. An elevating apparatus consisting ,of

the portable frame A and the endless travel- I ing carrier 0,1nounted on said frame, and pro-;

vided with hooks or rests G, substantially as herein described. i p 2, In an elevating apparatus, thefendless traveling carrier 0, consisting of the flexible 40 side chains, 0, mounted above and below on suitable pulleys, and the curved hooks or restsj G, secured to cross-bars mounted between the chains, substantially as herein described.

3. In an elevating. apparatus, the endless traveling carrier 0, consisting of the flexible side chains, 0, mounted above and below on suitable pulleys, the cross-bars F F, secured transversely between said chains, and the curved hooks or rests G, piv'oted or hinged by their upper ends on cross-banF, and guided loosely upon the cross-bar F, whereby they adjust themselves in conformity with the travel of the chains around the pulleys, upon which said chains are mounted, substantially 5' 5 as herein described.

4. Inan elevating apparatus, the endless chains 0 of the carrier, and the cross-bars F. F, carrying the hooks or rests, in combination with the means by which said bars are secured to the chains, consisting of the bolt f and'nut f and the notched clamping-yoke f, fitting the back of a link of the chain's, substantially as herein described.

5. The frame A of an elevating apparatus,
